The general process for customizing distribution boxes is as follows

# Requirement Communication and Scheme Design
1. **Clarify Usage Requirements**: Users should have in-depth communication with distribution box manufacturers or suppliers, and elaborate in detail on the usage scenarios of the distribution boxes, such as whether they are for home use, commercial buildings, or industrial plants. They also need to determine the functions required for the distribution boxes, such as whether they need to have leakage protection, overcurrent protection, metering functions, etc., as well as the types of loads and power ratings, such as lighting loads, power loads, or mixed loads, and the specific power values of each load.
2. **Design a Preliminary Scheme**: Based on the information provided by the users, the manufacturer conducts the preliminary scheme design of the distribution box, determines the type of the distribution box, such as fixed panel type, drawer type, or distribution cabinet type, etc., and plans the internal circuit layout, including the positions and connection methods of switches, sockets, busbars, protection devices, etc. At the same time, select appropriate electrical components, such as circuit breakers, contactors, relays, etc., to ensure that their performance and parameters meet the usage requirements.
3. **Scheme Review and Confirmation**: Submit the design scheme to the users for review, and explain in detail all aspects of the scheme, including the circuit principles, component selection, layout design, etc. The users review the scheme according to their actual needs and professional knowledge, put forward modification opinions and suggestions. Both parties communicate and adjust repeatedly until the users are satisfied with the scheme and confirm it.

### Material Procurement and Box Body Fabrication
1. **Procure Electrical Components**: According to the confirmed scheme, purchase all kinds of required electrical components. Select products with reliable quality and in line with national standards, and ensure that the specifications and models of the components are completely consistent with the design requirements. During the procurement process, strictly control the quality, inspect the components to check for any problems such as appearance damage or poor performance.
2. **Fabricate the Distribution Box Body**: Fabricate the body of the distribution box according to the design dimensions and requirements. The materials for the box body usually include cold-rolled steel plates, stainless steel, etc. Select appropriate materials according to the usage environment and budget. The fabrication process includes cutting, bending, welding, spraying and other processes to ensure that the box body has a firm structure, a flat appearance, accurate dimensions, and good protection performance, such as dust prevention, water prevention, corrosion prevention, etc.
3. **Component Assembly and Wiring**: Install the purchased electrical components into the distribution box according to the design layout. When installing, pay attention to the correct installation position of the components, ensure they are firmly fixed, and are convenient for operation and maintenance. Then carry out wiring. According to the circuit schematic diagram, use appropriate wires and cables for connection. The wiring should be neat, beautiful, and firm, avoiding crossing and confusion, and ensure that the specifications and colors of the wires meet the standard requirements for easy identification and maintenance.

### Inspection and Debugging
1. **Electrical Performance Inspection**: After the assembly is completed, conduct a comprehensive electrical performance inspection of the distribution box, including insulation resistance testing. Use an insulation resistance tester to measure the insulation resistance between each circuit and between the circuit and the box body to ensure that it meets the safety standards; grounding resistance testing, check whether the grounding system of the distribution box is in good condition and whether the grounding resistance is within the specified range; and also conduct a withstand voltage test, apply a certain voltage to the distribution box to detect whether it can withstand the specified voltage without breakdown, flashover and other phenomena.
2. **Function Debugging**: Debug various functions of the distribution box. For example, test the leakage protection function. By simulating a leakage fault, check whether the leakage protector can act in a timely manner and cut off the power supply; test the overcurrent protection function, adjust the load current, and observe whether the overcurrent protection device can act within the specified current value and time to protect the safety of the circuit and equipment; also conduct corresponding debugging for other functions, such as metering functions, remote control functions, etc., to ensure that they work normally.
3. **Problem Troubleshooting and Rectification**: During the inspection and debugging process, if any problems are found, promptly conduct troubleshooting and analysis to find out the causes of the problems, such as component damage, wiring errors, improper parameter settings, etc., and take corresponding rectification measures, such as replacing damaged components, correcting wiring errors, adjusting parameters, etc. After the rectification is completed, conduct inspection and debugging again until all the performance and functions of the distribution box meet the design requirements.

### Packaging and Delivery
1. **Packaging and Protection**: After the distribution box passes the inspection and debugging, carry out packaging. According to the size and weight of the distribution box, select appropriate packaging materials, such as cartons, wooden boxes, or foam plastics, etc., to wrap and fix the distribution box to prevent damage caused by collisions and vibrations during transportation. At the same time, mark the model, specifications, quantity, fragile item markings and other information on the packaging for easy identification and handling.
2. **Transportation and Delivery**: Select an appropriate transportation method to transport the distribution box to the location specified by the user. For relatively short distances, direct transportation by truck can be used; for longer distances, logistics transportation may be required. During the transportation process, ensure the safety of the distribution box and prevent it from being exposed to rain, getting damp, etc. After arriving at the destination, conduct handover with the user and provide relevant information about the distribution box, such as design drawings, operation manuals, inspection reports, etc., to ensure that the user can install and use it correctly.
3. **After-sales Service**: Provide after-sales service for a certain period. During the warranty period, if there are any quality problems with the distribution box, respond promptly and provide repair or replacement services. At the same time, provide technical support to the user, answer the questions encountered by the user during the use process, and guide the user to carry out daily maintenance and upkeep.
